Embodiment 1

[0093] (1) Preparation of modified tin fluorophosphate glass:

[0094] Take 3 parts by weight of 5 wt% silane coupling agent KH-550 solution, mix it with 90 parts by weight of tin fluorophosphate glass, and keep stirring in a beaker heated by a water bath at 75°C. After fully stirring for 1 hour, put it into a blast drying oven at 90°C for 24 hours, grind and disperse.

[0095] (2) Preparation of modified polypropylene:

[0096] Weigh 100 parts by weight of PP powder, add 3.5 parts by weight of MAH, 0.2 parts by weight of DCP and 0.1 part by weight of AIBN, simply mix the weighed reagents and pour them into a high-speed mixer to start mixing. 2.5 parts by weight of styrene was slowly added dropwise to the sample being mixed. After the dropwise addition, keep the mixing state of the mixer for 5 minutes until all the reagents are mixed evenly, then add the mixture into the feeding barrel of the twin-screw extruder, melt and graft under the action of the initiator AIBN and DCP,...

Embodiment 2

[0100] 30 parts of modified tin fluorophosphate glass prepared in Example 1, 70 parts of modified polypropylene and 0.4 parts of tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol parts by weight are uniformly mixed, melted and blended by a micro-injection molding machine for 5 minutes, and extruded into injection molding to obtain a modified tin fluorophosphate glass / polypropylene hybrid material. Processing temperature: 190° C., the prepared sample is a dumbbell-shaped spline of 35×10×2 mm.

Embodiment 3

[0108] (1) Preparation of modified tin fluorophosphate glass:

[0109] Take 3 parts by weight of 5 wt% silane coupling agent KH-550 solution, mix it with 90 parts by weight of tin fluorophosphate glass, and keep stirring in a beaker heated by a water bath at 75°C. After fully stirring for 1 hour, put it into a blast drying oven at 90°C for 24 hours, grind and disperse.

[0110] (2) Preparation of modified polypropylene:

[0111] Weigh 100 parts by weight of PP powder, add 6.5 parts by weight of MAH, 0.2 parts by weight of DCP and 0.1 part by weight of AIBN, briefly mix the weighed reagents and pour them into a high-speed mixer to start mixing. Keep the mixing state of the mixer for 5 minutes until all the reagents are mixed evenly, then add the mixture into the feeding barrel of the twin-screw extruder, melt and graft under the action of the initiator AIBN and DCP, and extrude to pelletize. Dry the prepared sample pellets. The graft ratio of maleic anhydride was 6.2%.

Abstract

The invention discloses a modified tin fluorphosphate glass / polypropylene hybrid material and a preparing method thereof and belongs to the technical field of high polymer materials. The hybrid material comprises the following ingredients, by weight part, of 70-90 parts of modified polypropylene, 10-30 parts of modified tin fluorphosphate glass and 0.4 part of antioxidant. The modified tin fluorphosphate glass is formed by tin fluorphosphate glass, and the surface of the modified tin fluorphosphate glass is processed by silane coupling agents. The modified polypropylene is formed by polypropylene, and the polypropylene is processed by maleic anhydride in a grafting mode. By means of modifying treatment, the interaction between the tin fluorphosphate glass and the polypropylene is enhanced, the compatibility between the tin fluorphosphate glass and the polypropylene is improved, and the mechanical property of the material is improved. The preparing method for the modified tin fluorphosphate glass / polypropylene hybrid material is simple and low in cost. The modified tin fluorphosphate glass / polypropylene hybrid material can be widely applied to fields of fibers and plastics and has good application prospect.

Description

technical field [0001] The invention belongs to an inorganic / organic hybrid material and a preparation method thereof, in particular to modified phosphate glass and modified polypropylene composite materials. Background technique [0002] Phosphate glass (Pglass) is an inorganic glass with a small network structure similar to a polymer. It has the characteristics of low glass transition temperature and stable chemical structure, and it exhibits Newtonian fluid in a wide range of temperature and frequency. rheological behavior. Introducing different cations into phosphate glass can obtain phosphate glasses with different structures and properties, such as lead phosphate glass, zinc alkali phosphate glass and tin fluorophosphate glass, among which tin fluorophosphate glass (TFP glass ) is the subject of current research. Tin fluorophosphate glass has a low glass transition temperature (Tg is about 55-155 ° C), which is within the processing temperature range of most polymers...
